Differential Unit problems of the 2009 Chrysler Aspen

I filed a complaint about the pinion nut and rear bearings issue to the NHTSA pinion nut recall - n08 - power train/driveline/differential unit. While stateline Chrysler representative, matt richardson, does not feel that the issue is related to the pinion nut recall, I strongly disagree. The reason stated for the when I press the gas that my car makes noise which appears to be coming from the front, but is actually coming from the rear, is because this is related to the rear end differential unit. Fact #1 ¿ my Aspen is 1 of the 11 million vehicles affected built by fca and part of the 2015 NHTSA enforcement action. Fact #2 - stateline Chrysler, fort mill, SC handled the recall for the pinion nut repair. Fact #3 ¿ July 2016, I was advised my car need pinion nut repair after the pinion nut repair service had been performed. Fact #4 ¿ during the same service, I was advised there was no rear differential fluid in my car by Chrysler and that it needed to be sealed. Which means my car¿s differential unit has not been lubricating. Fact #5 ¿ I was advised by Chrysler that the noise would go away after I paid to have oil ¿put into¿ the rear differential unit. I called matt to advise the noise had not gone away. On the third week, I took my car in and was advised the rear bearings need to be replaced at the cost of $2000. 00. Fact #6 ¿ I was advised by matt richardson my car will lock-up while driving. The failure happened at Chrysler which has impacted the way my car drives and my safety. This is truly 100% related to the n08 recall. Fca is accountable for its past failures and has committed to get unsafe vehicles repaired or off the roads, I did not receive any letter as agreed to by a consent order July 2015 with NHTSA, as fiat Chrysler agreed.
